I note a paper supporting the hypothesis that bushfires can cause rainfall. They do this by fertilising the ocean (smoke and ash) and causing phytoplankton blooms. These increase rainfall by trapping more heat in the ocean surface and via the cloud seeding effect of the dimethyl sulphide produced (along with other volatile sulphur compounds).

This raises the question of whether it might be feasible to create rainfall events artificially. If viable, it could become a means of preventing disaster, helping farmers, and perhaps even making oceans more productive.

The UN currently has a ban on ocean fertilisation, a mindset even more idiotic than Australia's nuclear ban. So next time the bush is ablaze, thank the UN for banning research that might prevent disasters and save lives.
